# CanGrow
|
|
|
|
|
|
|
|
|
|
|
|
A simple DIY plant growing system (for cannabis).
|
|
|
|
|
|
|
|
# WORK IN PROGRESS
|
|
|
|
## Motivation
|
|
|
|
I want to build a simple grow system, which I can power by my off-grid
|
|
12V solar system. So this project is limited to a small 40x40x120 tent
|
|
for one plant with a 50W 12V grow LED light.
|
|
|
|
As I did it for my solar system, the measurements of this project will be shown
|
|
on my website. For that a REST API is planned.
|
|
|
|
I want to automate as much as possible which makes sense and is easy to build.
|
|
|
|
## Features / ToDo List
|
|
|
|
- Measure values :white_check_mark:
|
|
- Humidity :white_check_mark:
|
|
- soil moisture :white_check_mark:
|
|
- temperature :white_check_mark:
|
|
- water level for water tank :white_check_mark:
|
|
- LED grow light control (on/off, dimming, max. 12V 50W load ) :large_blue_circle:
|
|
- You can of course use a relais as well, if you want to drive 220V lights
|
|
- fan control (on/off, (PWM?) max 1A) :large_blue_circle:
|
|
- pump control for automatic watering (max 1A) :large_blue_circle:
|
|
- Web UI and REST API for data and controlling :red_circle:
|
|
- simple web ui
|
|
- Send notifications with web call (e.g. for mastodon)
|
|
- predefined grow profiles
|
|
- persistend data
|
|
- Start of Grow
|
|
- day of grow
|
|
- grow profile
|
|
- watering amount per week
|
|
- light cycle
|
|
- wifi settings
|
|
- settings in general
|
|
- Easy to build and use for beginners (i hope so!) :red_circle:
|
|
- easy to build up on a perfboard
|
|
- easy to etch pcb
|
|
- easy to access and modify
|
|
- low cost as possible!
|
|
|
|
:white_check_mark: Done - :large_blue_circle: In Progress - :red_circle: ToDo

## Parts used
|
|
|
|
- ESP8266 D1 mini
|
|
- DHT11 humidity and temp sensor
|
|
- I2C soil moisture sensor: https://github.com/Miceuz/i2c-moisture-sensor / https://eu.robotshop.com/de/products/i2c-soil-moisture-sensor
|
|
- the I2C module is for some people too expensive, I plan support for those cheap capacitive sensors: https://www.az-delivery.de/products/bodenfeuchte-sensor-modul-v1-2
|
|
|
|
- 50W LED 12V full spectrum grow light: https://www.ebay.de/itm/354322466159
|
|
- MOSFETS (some i have fyling around, IRF3205, IRF3710, BUZZ11...)
|
|
- 12V 4W water pump set https://www.ebay.de/itm/394413649692
